EETimes bericht dat Hitachi als gevolg van de nuclaire ramp in Tokaimura een aantal fabrieken plat heeft moeten leggen, waaronder enkele 64 en 256Mbit DRAM production plants:
An accident at a a nearby uranium-processing plant forced Hitachi Ltd. to suspend its manufacturing operations, including those at a leading-edge semiconductor fabrication facility, on Friday (Oct. 1).
[...] Hitachi has 11 plants and a laboratory within the 10-km range, resulting in the evacuation and closing of all the facilities in Hitachinaka and Hitachi City, where the company was founded. Hitachi said it would resume normal operations by Friday evening.
The plants affected include the Digital Media Products Division, which produces cell phones and DVD-RAM drives, and the most advanced IC fab of
Hitachi's Semiconductor & Integrated Circuits Division, which upgraded the fab to 0.18-micron design rules late last year. The Naka fab produces 64- and 256-Mbit DRAMs as well as advanced logic products such as the SH series processors, a Hitachi spokesman said.
Hitachi makes 30,000 256-Mbit DRAMs per month at Naka. The spokesman could not determine how much total production was lost on Friday, nor whether the unexpected work stoppage caused any damage.
Als het goed is draait alles nu dus weer.
